Basically we would like to avoid passing through a network node when it's not needed, to avoid a potential bottleneck + SPoF. With Juno there is also the Distributed Routing (DVR) option if you are using Floating IPs, but we haven't tested it yet, and still has some disadvantages. In the setup described, the router used by the VMs is an external router (actually 2 routers in VRRP), the traffic from the VM goes directly to the router, and there is no encapsulation involved. This should increase speed an reliability. .a. -- antonio.s.mess...@gmail.com antonio.mess...@uzh.ch +41 (0)44 635 42 22 S3IT: Service and Support for Science IT http://www.s3it.uzh.ch/ University of Zurich Winterthurerstrasse 190 CH-8057 Zurich Switzerland _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack
